This article is complete junk and I thought better of the Torygraph...
Milder winters in future could lead to an increase in numbers of Canada geese at the MoD’s offices at Abbey Wood in Bristol. This could result in the birds colliding with buildings on the site

Who gives a rat's arse about Canada Geese hitting buildings? What makes Abbeywood's buildings more likely to be hit than any other 3 storey buildings in and around Bristol (or the rest of the country). Canada Geese aren't flying into buildings on a regular basis at other locations where they already flock - unless of course all the ones at Abbeywood are blind!
